Data given
Liquid Limit (LL)=45%Plastic Limit (PL)=18%
Clay content=24.2%(particle <2 micro meter)
moisture content is 29%

| Liquid limit and plastic limit |
1. Calculating Activity of Soil
Plasticity Index = liquid limit - plastic limit
Plasticity Index = 45-18 = 27
Activity = Plasticity index/(%clay content )
= 27/24.2
=1.115
2. Calculate liquidity index
Liquidy Index= (Natural water content – Plastic limit)/(liquid limit-Plastic limit)
=(29-18)/(45-18)
=11/27
=0.407
